Application filed January 19, 1906. Serial No. 296,789.

To all whom it may concern:

Be it known that I, WILLIAM H. Down, a citizen of the United States, residin at the city of New York, in the borough o Brooklyn and State of New York, have invented certain new and useful Improvements in Bottle-Stoppers, of which the following is a full, clear, and exact description.

M invention relates to bottle-caps, and has or its principal object to provide a cap of cheap construction and ca able of sealing a bottle efficiently and which is easily removable by the purchaser without requiring any special tools or difficult manipulatlon.

With this object in view my invention consists in the construction of cap hereinafter set forth and shown and finally particularly pointed out in the appended claim;

In the drawings, Figure 1 is a perspective view of a cap embodying the principles of my invention. Fig. 2 is a sectional view of the same applied to a bottle. Fig. 3 isa side view.

Bottlecaps are now produced and are in common use which are sufficiently cheap and efiicient for sealing a receptacle; but so far as I am aware, none of the forms having sufficient cheapness and practical efficiency in sealing a bottle have been removable without special tools or manipulating a plurality of different parts or elements thereon. In other words, the desideratum of a cap which will efficiently seal abottle, but which is removable by merely opening a single ta with the fingers, has not yet been attaine In carrying out the resent invention aim to provide a cap of t 1is character.

Referring to the drawings, in which like parts are designated b the same referencesign, 1 denotes a cap of sheet metal or other suitable material having a top plate 2 and a circumferential depending rim 3 stamped or formed thereon. 4 indicates depending tags or fingers upon the rim, each of which is embossed or beaded at 5, so as to engage the bottle-neck, and has a lower extending part or extremity 6, which serves as an engaging-point for the fingers when it is desired to remove the cap from the bottle.

7 denotes the usual packing or sealing disk of cork or analogous material.

The beads 5 are preferably embossed directly upon the material of'the depending the three tags or fingers. practlce more or less lrregular, and 1t 1s absogreater effective length than would be thecase if they extended directly from the lower edge of the rim. I arrange the depending fingers 4 in a special way, which constitutes a very important feature of my invention.

Each of the tags or fingers depends from the cap at a point exactly one hundred and twenty degrees from the others. In other words, the three fingers are triangularly related to one another, and in this way it is possible to clamp the cap u on the bottle with the necessary practical efficiency and yet enable its removal by the bending of a single finger.

The use of the invention is as follows: The cap, being placed upon a bottle, is clamped into sealing relation in the usual way by pressing inward the various'de ending tags or fingers,'so that their beade portions 5 engage the usual inclined wall A, Fig. 2, of the bottle and draw the cap downward thereon. In this wa the cap is placed in sealing relation on the bottle and remains so as long as desired. This is by reason of the symmetrical character of the drawing forces produced by Bottle-necks are in lutely essential to have at least three points of drawing engagement in order to enable the cap 'to be properly borne down thereon. At the same time the arrangement. of three equally-spaced tags or fingers permits tl removal of the cap by bending any one of them, since the remaining two are not sufficiently spaced apart to hold the cap upon the bottle any one of the tags is bent or broken. When, therefore, it is desired to open the bottle, it is merely necessary to pry one of the tags laterally with the fingers or thumb-nail, by which it is bent at its point of junction with the rim. The stiffening action of the bead 5 is important in this connection in that it insures the opening of the tag or finger at the undercut or notched, as

point required and not at a point in the line of the bead. If, however, the tag should fail to bend at the proper point or should not wholly release the cap, it is possible to repeat the process with another finger or tag until all of the three have been bent. Under ordie nary circumstances the cap is releasable by the single iinger or tag initially bent.

What I claim is A bottle-cap comprising a top plate having a circumferential depending rim, three tags or fingers depending from said rim and equally spaced at distances of one hundred and twenty degrees thereabout, beads embossed upon said tags or fingers to extend partly across the width thereof and adapted, to engage the usual inclined wall of a bottle- WlLLlAM il. now it.
